Where is Thy Sting

Hmm, I turn the keys in the cores destroyed
Like a nerve in the scarf of scarlet
Now who'll let them come kind
Who, I cannot
On whom I caretake comes the reddest halo

I unearth thy dumb dead-end in death
Inhumed I can dump the head in death
I wonder through what the hell I'm doing
Hmm, I can hum the ending sign
No doubt I can hum the dead-end days
